2. About Safety
2.1 Important Safety Instructions
The MI-600T/MI-700T/MI-800T Microinverter is designed and tested according to international safety
requirements. However, certain safety precautions must be taken when installing and operating this
microinverter. The installer must read and follow all instructions, precautions and warnings in this installation
manual.
•
All operations including transport, installation, start-up and maintenance must be carried out by
qualified and trained personnel.
•
Before installation, check the unit to ensure that it is free of any transport or handling damage,
which could affect insulation integrity or safety clearances. Choose an installation location carefully
and adhere to the specified cooling requirements. Unauthorized removal of necessary protections,
improper use, and incorrect installation and operation may result in serious safety and shock hazards
or equipment damage.
•
Before connecting the microinverter to the power distribution grid, contact the local power
distribution grid company to obtain the appropriate approvals. This connection must be made only
by qualified technical personnel. It is the responsibility of the installer to provide external disconnect
switches and Overcurrent Protection Devices (OCPD).
•
Only one PV module can be connected to one input of the microinverter. Do not connect batteries or
other power supply sources. The microinverter can be used only if all the technical characteristics are
observed and applied.
•
Do not install the equipment in adverse environments, such as environments that are flammable,
explosive, corrosive, extremely hot or cold, or humid. Do not use the equipment when the safety
devices do not work or are disabled.
•
Always use personal protective equipment, including gloves and eye protection, while installing.
•
Inform the manufacturer of non-standard installation conditions.
•
Do not use the equipment if any anomalies are discovered while operating. Avoid temporary repairs.
•
All repairs should be carried out by using only qualified spare parts, which must be installed in
accordance with their intended use and by a licensed contractor or authorized Hoymiles service
representative.
•
Any liability arising from commercial components are delegated to their respective manufacturers.
•
Any time the microinverter has been disconnected from the public network, please be extremely
cautious, as some components can retain charge sufficient to create a shock hazard. Prior to
touching any part of the microinverter, please ensure that surfaces and equipment are under safe
touch temperatures and voltage potentials before proceeding.
•
Hoymiles accepts no liability for damage due to incorrect or improper operation.
•
Electrical Installation & Maintenance shall be conducted by a licensed electrician and shall comply
with local wiring regulations.
